PAPER-REGISTERING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 632,449, dated. September 5, 1899.

Application filed December 15, 1898. Serial No. 699,33 7. (No model.)

To all whom, it may concern:

Be it known that I, TALBOT C. DEXTER, a citizen of the United States, and a resident of Pearl River, in the county of Rockland, in the State of New York, have invented new and useful Improvements in Paper-Registering Instruments, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of paperregistering instruments which are provided with vertically-movable pins entering perforations in the underlying sheet.

The object of the invention is to provide a registering instrument which shall be of utmost simplicity in construction and efiicient in operation; and to that end the invention consists, chiefly, in the combination, with the shectconveying tapes, front stop, and sheetsupporting bars, of a carrier disposed stationary above said bars, a lever pivoted to said carrier, mechanism imparting intermittent oscillatory motion to said lover, a vertical guide on the carrier, a conically-pointed registering-pin suspended from the aforesaid lever and sliding in said guide, and a spring transmitting downward pressure from the lever to the pin; and the invention also consists in novel features of its details, as hereinafter more fully described.

In the accompanying drawings, Figure 1 is a side elevation of a paper-folding machine equipped with my improved registering instrument. Figs. 2 and 3 are plan views of the rear and front portions, respectively, of said machine. Fig. 4 is an enlarged side view of the registering instrument in its sheet--registering position. Fig. 5 is an enlarged side view showing said registering instrument in connection-with the movable front stop. Fig. 6 is a side view of a modification of the registering instrument, and Fig. 7 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

A represents the main frame of a paperfolding machine. 13 B denote the first pair of folding-rollers. The majority of such machines are provided with additional foldingrollers. (Not shown in this case.)

a (1 represent the tapes which convey the paper into the machine. Said tapes run on the feed-roller O and in grooves in the rear folding-roller B. l

D are the usual drop-rollers over the afore* said feed-roller.

b l) are the usual paper-supporting bars, which are arranged between the tapes a a.

c designates the front stop, which arrests the movement of the delivered sheet and is adjustable toward and from the folding-roller to suit the diiferent sizes of sheets to be folded.

E designates the blade which introduces the delivered sheet into the bite of the foldingroller, and d d are the usual paper-supporting bars, which extend from the folding-rollers to the front end of the machine.

6 represents a rigid horizontal bar which is sustained transversely above the papersupporting bars dd by means of posts e, mounted on the sides of the main frame A. Upon said transverse bar are mounted longitudinally-adjustable brackets ff, from each of which extends at right angles toward the folding-rollers B B a horizontal arm g, which is adjustable vertically on the bracket f. On said arm rides a carrier F, which is adapted to be shifted lengthwise the arm and adjustably securedin its required position, preferably by means of a screw h, jonrnaled in an ear h on the arm g and passing through a screw-threaded ear k on the carrier, as clearly shown in Figs. 1 and 3 of the drawings. The aforesaid adjustabilities of the brackets f and carrier F are essential to adapt the registering instrument to operate on sheets of different sizes and on sheets having the perforations in different positions. Said carrier has rigidly attached to it or integral with it a vertical guide t', in which slides the vertical sheet-registering pin P, the lower end of which is formed with ,a conical or tapered point P for entering a perforation, preferably of circular form, in the un erlying sheet of paper. (Indicated by th dotted line at.)

The vertical guide '11 serves to maintain the registering-pin axially in the line of its vertical movement, so that in the descent of said pin the tapered or conical point P thereof entering the perforation in the paper acts as a wedge, which by contact with the front edge of the perforation in the paper pushes the sheet to its registering position.

For operating the registering-pin P, I preferably pivot to the carrier F a bell-crank or suitable lever j, one arm of which carries in a suspended position the registering-pin, which is provided with a head P on its upper end and with a shoulder P beneath the leverarm, and between said shoulder and arm is interposed a spiral springj', surrounding the upper end portion of the pin, said spring serving to transmit downward pressure from the lever j to the registering-pin, so as to insure the entrance of the tapering point of the pin into the perforation in the paper and push said paper to its registering position. To further insure said effect, the paper-supporting plate 02 is disposed directly under the registering-pin and provided with a ver tical orifice for the reception of the registering-point P. The lever j receives in termittent oscillatory motion from a pitman 7:, connecting one of the arms of said lever to an arm fastened to a'rock-shaft Z, to the end of which is attached a lever Z, which has its free end bearing on a rotary cam 1 In order to facilitate the movement of the sheet to its registering position, I employ suitable means for relieving the sheet from frictional contact with the tapes a a during said movement. This I preferably accomplish by' carrying said tapes on vertically-movable supports which cause the tapes to be lowered to a plane beneath the usual paper-supporting bars I) 1) between the tapes. Said vertically-movable supports may consist of rollers O mountedon shafts n, which extend across the machine beneath the tapes and pass with their ends through vertical guides 71, secured to the sides of the main frame A. Said ends of the shafts are pivoted to the upper ends of toggles 0 o, the lower ends of which are pivoted to suitable supports 0 fastened to the frame, as illustrated in Fig. 1 of the drawings.

The toggles on each side of the machine are connected together by a rod 1) and are actuated by a pitman p, which receivesint-ermittent reciprocating motion from a cam r.

In the operation of the machine the paper is fed in upon the feed-roller C, from whence it is carried into the machine by the tapes a a, which atthattimearein a plane to obtain the necessary frictional hold upon the paper to carryit forward to the front stop 0, which arrests said movement. The paper is then shifted laterally to side-register by a suitable registering instrument, (indicated by dotted lines at s in Fig. 3 of the drawings,) which instru ment may be of the form of the gripper and its actuating mechanism clearly shown in my Letters Patent No. 599,319, dated February 22, 1898, and inasmuch as I do not in the present case limit myself to any special form of said lateral-registerin g instrument it is unnecessary to describe the same in detail here. This registering of the paper carries it into 1 motion.

position to allow the registering-pins P to enter the perforations in the paper. Either before or immediately after said lateral registering of the paper the toggles o o are actuated to lower the rollers 0 0, which during.

their elevated position have their tops in a plane slightly higher than the top of the feedroller 0 and the tops of the tape-carrying portions of the folding-roller B. In lowering the aforesaid rollers 0 0 the tapes are allowed to drop sufficiently beneath the plane of the paper-supporting bars I) to cause the paper to ride on said bars and to be carried thereby out of contact with the tapes. The registering-pins P Pthen descend and enter their conical or tapering points P P into the perforations in the paper. Said pins being maintained axially in the lines of their vertical movement and incapable of yielding laterally in any direction causes the tapering front sides of said points to crowd against the adjacent edges of the perforations, and thereby push the paperforward to its longitudinal registering position. As soon as this is effected the pins P P rise to release the paper, and then the blade E tucks the paper into the bite of the folding-rollers B B, which draw the sheet down between them and impart the first fold to the sheet. the sheet has thus been Withdrawn from the As soon as top of the machine the toggles 0 0 are again folding-blade E is required to be so timed in its movement as to cause it to touch the sheet just as the points of pins P P are withdrawn from the perforations in the paper. In this manner the sheet will be accurately folded; but in most cases the front stop a is required to be movable toand from its sheet-arresting position and timed to recede from said position before the registering-pins enter the perforations in the paper. The arrangement of this alternately advancing and receding front I stop is shown in Fig.5 of the drawings,in which the front stop 0 is attached to longitudinal bars II, sliding in guides II, attached to the stationary cross-bar e. The outer end of each bar H has attached to it a wrist-pin 11, which is straddled by the longitudinally-slotted end of an arm I, attached'to a shaft 1', which extends across the machine and is mounted n suitable bearings L, attached to the frame A. To one end of this shaft is fastened a lever L, the free end of which has pivoted to it a roller i, by which it rides on a cam L and receives therefrom an intermittent rocking The cam L is shaped to cause the front stop 0 to move to its sheet-arresting position in time to secure the impact of the front edge of the incoming sheet and to recede from IIO said position immediately before the registering-pins P P enter into the perforations in the underlying sheet, and thus permit said sheet to be pushed forward by the tapering or conical points of said pins pressing on the adjacent edges of the perforations.

I wish it to be understood that I do not limit myself to the hereinbefore-described vertical guide 1' on the carrier F for maintaining the registering-pin axially in the line of its vertical movement, as the same result may be attained by forming said pin integral with an arm a, attached to a shaft a, which extends across the machine and is mounted in bearings on posts 16 secured to the sides of the frame A, as represented in Figs. (3 and 7 of the drawings. To one end of the shaft 1/. is secured an arm n which is connected to a vertical pitman r, sliding in a vertical guide r, attached to the frame A. The lower end of this pitman has pivoted to ita roller 1*, by which it rides on a rotary cam 11'.

In order to permit said instument to be adjusted for different-sized sheets of paper, 1 fasten the arm a to the shaft u by means of set-screw u, which can be loosened to allow the arm to be shifted lengthwise of the shaft and secured in its desired position, tightening said screw. This permits lateral adjustment of the registering-pin. To permit longitudinal adjustment of said pin, 1; provide the frame A with longitudinal slots 11. for the reception of the bolts a, by which the posts are fastened to the frame. To maintain the arm a in connection with the pitmau 1) during said longitudinal adjustment, I rigidly secure to the upper end of said pitman a horizontal plate 12 which is provided with a longitudinal slot o for the reception of the bolt v which connects the arm a to the pitman.

\Vhat I claim as my invention is- 1. In combination with the sheet-conveying tapes, front stop and sheet-supporting bars, a carrier disposed stationary above said bars, a lever pivoted to said carrier, mechanism imparting intermittent oscillatory motion to said lever, a vertical guide on the carrier, a comically-pointed registering-pin suspended from the aforesaid lever and sliding in said guide, and aspring transmitting downward pressure from the lever to the pin.
